小弟刚到公司上班,我们老大叫我利用libevent里面的一些接口,写一个从公司网页上发送消息(请求)到Psi(时通讯用户连线聊天)的接口程序,借鉴的libevent接口为如下所示,小弟这方面真是一点不懂啊,可能连问题都说不清楚,不好意思,希望那个高手大哥指点指点。。。。万分感谢
#include <sys/types.h>
#include <sys/time.h>
#include <stdlib.h>
#include <err.h>
#include <event.h>
#include <evhttp.h>
void root_handler(struct evhttp_request *req, void *arg)
{
struct evbuffer *buf;
buf = evbuffer_new();
if (buf == NULL)
err(1, “failed to create response buffer”);
evbuffer_add_printf(buf, “Hello World!\n”);
evhttp_send_reply(req, HTTP_OK, “OK”, buf);
}
void generic_handler(struct evhttp_request *req, void *arg)
{
struct evbuffer *buf;
buf = evbuffer_new();
if (buf == NULL)
err(1, “failed to create response buffer”);
evbuffer_add_printf(buf, “Requested: %s\n”, evhttp_request_uri(req));
evhttp_send_reply(req, HTTP_OK, “OK”, buf);
}
int main(int argc, char **argv)
{
struct evhttp *httpd;
event_init();
httpd = evhttp_start(“0.0.0.0″, 8080);
/* Set a callback for requests to “/”. */
evhttp_set_cb(httpd, “/”, root_handler, NULL);
/* Set a callback for all other requests. */
evhttp_set_gencb(httpd, generic_handler, NULL);
event_dispatch();
/* Not reached in this code as it is now. */
evhttp_free(httpd);
return 0;
